OK. Got a chance today to kind of test out the Caldwell G2. Overall impression was it's OK. Shot maybe 80 rounds of hand load 9mm and about 50 rounds of hand load .357 Sig. Overall, most impressed with ease of set up. I can leave this assembled on my shooting bench and just wip it out doors and start shooting. Comes with it's own tripod which is kind of cheesy but sufficient for the task. Connects pretty easy to my cell phone, LG Droid something or other. Missed maybe five shots out of the 130 sent down range. I will ring this out further against the Oehler. See what difference between the two there is.
